mike, 13 Feb 2014not much difference , if any at all , extra setting on white balance and improve wifi , no big deal Battery life does not have any improvement and still depletes faster? What an update.. What did u use to update your ultra?

z ultra user , 12 Feb 2014Who among you upgraded their phone to .136?
Hows it going? Hows the batt life? not much difference , if any at all , extra setting on white balance and improve wifi , no big deal

....contd....after 2 months of usage , i agree its a premium phone with lots of goodies

but the biggest killer is sony opt to water proof this phone at the expense that hurts the very basic function of what a phone is supposed to do , ie , phonecall ....

by adding membrane in every conceivable pots and holes and slits , sony is making the phone very hard to use for calling .......i dont need the water proof thingy but i pay teh price for that ...

this is your nightmare come true, it shouldn't even happen 2o years ago .....

First in come the paltry ringtone, assuming u have ears the size of a bat and manage to answer the call , the ear piece slit - the width is almost half of other phone like mega6.3.....which means position the slit correctly against your face so the sound can enter your auditory channel correctly becomes a difficult task , if not impossible .......a wrong placement or press the phone too hard on your cheek u hear nothing .......even if u manage it all , the ear piece sound output is way below average ....so u smart guys will say use speaker phone, buts its not much better in reality ....i have numerous fight over this is my callers in missed calls, bad voice etc

i hope u guys can share with me on this and i even had teh xloud setting on ....i am on the verge of giving up and just use it as a tablet and buy a cheap nokia to answer call , its that pathetic ....

just word of warning to u z ultra lovers....i bought the sbh52 headset which not only is a pretty handsome unit but packs speaker phone function so u dont have to stick an ear bud to the ear etc etc

i thought it was a marriage made in heaven , you kinda need this headset cos of the sheer size of the ultra, the weight , thinness which makes it prone to fall , not to mention the weak ringtone, speaker output and the small ear piece slit which makes it hard to listen to via your ears .......

then the sbh52 just drop off, disconnect and comes all sort of bugs u think u r in amazon jungle , later on i spot the same many sad stories from google play ( search sbh52 and rea the forums , i kid you not ) ......

i dont mind paying premium for a same brand premium headset out of neccesity or sheer beauty but if sony cant even make this work being the same family line, i am just lost with words .....esp if u have upgrade to 4.3 .....

basem, 10 Feb 2014guys i heard some issues about the screen which turned black and there is no responsive in son... moreThose were the 1st production of z ultra. But nowadays i dnt thnk thats still the issue! Buy if you want. Dont buy if you hesitate.

guys i heard some issues about the screen which turned black and there is no responsive in sony mobiles since sony launched xperia s ---is that problem still here in that phablet coz i need that mobile badly and coz of the previous reason am hesitate about buying that phone

Hey hurrryy.....
I got it Real BOMB last sturday.....
Its amaging bro. Screen Qwalty no word to i say
Its very slim and light weight as size
This phone is not for weak heart, if u want good phone ,fast prossasor , just go and pick it.
If u no matter of size (actuly size is very comfortable becouse its very slim ) then u buy it
I got it via flipcart at rup 35999/- indian price
GO GO GO GO ....... pickup

Awesome phone if u r thinking of buying it don't think much
Everything is so good in this phone that it hard to find its drawbacks. I bought it three weeks ago and I am very happy with it, design is so beautiful that I want to keep it touching again and again.
Performance is as smooth and silky as butter 2.2 Ghz what else do you want
When I play games it gives a wonderful feeling coz of increased graphics performance
I had upgraded it from 4.2.2 to 4.3 and its performance improved
Camera is quite satisfactory it would be really good if it had flash
Only thing I wish it had 32 GB of internal memory.

i used this for 3 days.. many missed calls because of very low phonering even i set to the maximal sound. camera without flash.. i couldn't take picture in evening aroubd 5pm. I switched to samsung mega 6.3.. lot better.

the msin thing if your gonna buy this phone is on the storage of apps.Which you could not move apps through the sd card wich sucks especially if you wanna install big games .MINe is 12 gg of internal memory one thing i think its better if you root upgrade it to play such games like modern combat 4 etc and you can download folder mount wich root is requiered .If you will buy this phone you need to choose between this one and the note 3 .
